Packing Configuration

Use Packing Configuration to control how Mighty suggests packages and how far an eligible order can move automatically. Automation always stops at Ready to Ship so a person can review the packages, rate, and label before completing fulfillment.

​

Open Packing Configuration

1. Open Settings.
2. Choose Entity Settings.
3. Open Shipping and Fulfillment.
4. Choose Packing Configuration.

​

Set Mighty Parameters

Use the seven parameters together to tune package suggestions:

• Base Per Box ($): adds a cost for each suggested box. A higher value generally favors fewer boxes.
• Per Lb ($): represents the cost associated with package weight.
• Oversize Penalty ($): adds a cost when a suggestion exceeds the oversize limit.
• Oversize Limit (in): sets the dimension at which the oversize penalty applies.
• DIM Weight Factor: accounts for the space a package occupies when comparing options.
• Epsilon: allows a small fit tolerance for dimensions that are nearly equal.
• Repack labor per box ($): represents the labor cost of moving items into a different box during repacking.

Choose Save Parameters after changing these values. This button saves the parameter values separately from the automation settings.

​

Configure Pack Automation

Auto-suggest Mighty cartons creates a package suggestion for an eligible order.

• Auto-pack orders on payment: starts packing when an eligible order becomes fully paid.
• Auto-pack net-terms orders on confirm: starts packing when an eligible net-terms order is confirmed.

The auto-suggest toggle and both pack triggers save immediately when you change them. Before enabling a trigger broadly, confirm that products have accurate dimensions, weight, packaging classification, packing category, serial tracking, and freight data. Missing setup can cause the order to wait for a person.

​

Configure Rate Automation

Rate automation controls when rates are requested and how an available rate is selected:

• Auto-fetch rates when package is created: requests rates when a package is added.
• Auto-select cheapest rate: selects the lowest available rate when rates are returned.
• Auto-fetch rates on pack: requests rates when packing finishes.
• When no rates are available: choose one of these responses:
  • Show warning to user: stop and show the issue for a person to resolve.
  • Use flat rate from shipping rules: use the applicable flat rate from Shipping Rules.

Choose Save automation settings after changing rate fields.

​

Configure Label Auto-Buy

Label auto-buy uses the intended service from an order-level override or a matching shipping rule. That service is never silently downgraded.

• Auto-buy label on pack (manual and walk-in orders): buys a label when an eligible manual or walk-in order is packed.
• Auto-buy label on channel orders: buys a label when an eligible channel order is packed. This option requires Auto-pack orders on payment to be enabled.
• Auto-buy by default: for eligible manual and walk-in orders, allows a matching rule with one intended service to auto-buy a label even when that rule does not explicitly enable auto-buy. Channel orders use Auto-buy label on channel orders.
• Fallback services (when no shipping rule matches): defines the services Arcus is allowed to consider. The list is an allowlist, not a preference order. Mighty buys the cheapest eligible returned rate within the allowed set. Fallback applies only when there is no matching rule and no order-level override. An empty list buys no label.
• Re-rate Charge Threshold ($): sets the allowed difference between the label cost and the amount charged to the customer. When the difference exceeds the threshold, Arcus prompts the operator to recharge the customer, absorb the difference, or handle it manually. It does not require a new rate.

Choose Save automation settings after changing rate or label fields. Even when a label is purchased, the order stops at Ready to Ship for review and manual fulfillment completion.

Manage Packing Presets

Packing Presets let you save parameter combinations for repeatable testing and operations.

• System Default supports Test Pack only. You cannot edit it, delete it, or select it as a custom default.
• Custom presets support Add, Edit, Delete, Test Pack, and Set Default.
• Set Default makes that custom preset the starting configuration for Mighty.

​

Preview With Test Pack

Choose Test Pack on System Default or a custom preset. In the Test Pack Console, edit the sample Items and Boxes, including dimensions, weight, quantity, category, and box capacity as needed. Keep at least one item and one box, then choose Run Test Pack. Review the proposed packed boxes, item placement, and leftovers. If the preview is not practical, adjust the sample Items, sample Boxes, or preset and run it again. Test Pack writes nothing: it creates no packages or labels and does not change fulfillment, inventory, accounting, or saved settings.

​

Product Data Mighty Depends On

Review these fields before changing parameters to compensate for a data problem:

• Product dimensions, weight, and measurement units.
• Packaging classification and packing category.
• Box products and prepackaged configurations.
• Serial tracking requirements.
• Freight and shipping information.
• Available inventory and bin assignments.

​

Common Blocks

• No suggestion appears: check the pack trigger, product dimensions, weight, inventory, bins, serial requirements, and freight handling.
• Too many boxes are suggested: verify item and box dimensions, then review Base Per Box ($) and packing categories.
• An oversized box is suggested: verify dimensions, then review Oversize Limit (in) and Oversize Penalty ($).
• No rate is available: check Shippo, ship-from and destination addresses, package data, allowed services, and the selected no-rates response.
• No label is purchased: check the order override, matching shipping rule, fallback services, Shippo connection, and address validation.
• An order waits at Ready to Ship: review the packages, selected service, rate, and label, then complete fulfillment manually.
